Commentary from the Sefer Ruach Chaim by Rabbi Chaim of Volozhin.
Rabbi Chanania ben Akashia says: The Holy One, Blessed is He, wishes to confer merit upon Yisra’el; therefore He gave them Torah and mitzvoth in abundance, as it is said (Yeshiyahu 42:21): “HaShem desired, for the sake of His righteousness, that the Torah be made great and glorious.”
